Consider a wood block of mass 1.00 kg, tied to a massless string of length 2.00 m, that is shot with a bullet of mass 5.00 g and a speed v = 400 m/s. The bullet goes through the block and continues out the other side, but with a smaller velocity. Treat the block as a point-like mass. i. What is the angular momentum of the bullet about the point where the string is tied? ii. If the block eventually rises to a height 0.45 m above its initial height, what is its velocity just after the collision? What is its angular mometum? iii. What is the angular momentum of the bullet immediately after the collision, since angular momentum is conserved? What is the velocity of the bullet after the collision?
